The objective was to evaluate a reforestation carried out by the goldwashers. The studied area is situated along the Gualaxo do Norte river margins in Mariana - MG. The seedlings were received by donation of regional nurseries and were planted on December of 2006 in hole of 25x25 cm and plant spacing 3x2 meters. The evaluations were carried through on March of 2007. The height was measured with metric ribbon and the diameter, 5 cm above the ground, was done by using digital pachymeter. They planted 538 seedlings of 20 different species, pertaining to twelve botanical families. The most abundant species were Enterolobium  contortisiliquum (96), Mimosa schomburgkii (76) and Chorisia speciosa (45). It was not possible to identify 19 individuals due to...

Lattice-work corridors for climate change: a conceptual framework for biodiversity conservation and social-ecological resilience in a tropical elevational gradient
Provedor de dados: Ecology and Society
Autores: Townsend, Patricia A; University of Washington; ptownsen@uw.edu; Masters, Karen L; Council on International Educational Exchange; KMasters@ciee.org.
Rapid climate change poses complex challenges for conservation, especially in tropical developing countries where biodiversity is high while financial and technical resources are limited. The complexity is heightened by uncertainty in predicted effects, both for ecological systems and human communities that depend heavily on natural resource extraction and use. Effective conservation plans and measures must be inexpensive, fast-acting, and able to increase the resilience of both the ecosystem and the social-ecological system. We present conservation practitioners with a framework that strategically integrates climate change planning into connectivity measures for tropical mountain ecosystems in Costa Rica. We propose a strategy for doubling the amount of...

Losses of forest cover, biodiversity, agricultural productivity, and ecosystem services in the Himalayan mountain region are interlinked problems and threats to the sustainable livelihoods of 115 x 106 mountain people as well as the inhabitants of the adjoining Indo-gangetic plains. Until the 1970s, environmental conservation, food security, and rural economic development were treated as independent sectors. The poor outcomes of sector-oriented approaches catalyzed efforts to address environmental and socioeconomic problems concurrently. The identification of "key" natural resource management interventions is an important dimension of integrated management. Projects to rehabilitate the degraded lands that cover 40% of the Indian Himalaya could be key...

Rebuilding Resilience in the Sahel: Regreening in the Maradi and Zinder Regions of Niger
Provedor de dados: Ecology and Society

The societies and ecosystems of the Nigerien Sahel appeared increasingly vulnerable to climatic and economic uncertainty in the late twentieth century. Severe episodes of drought and famine drove massive livestock losses and human migration and mortality. Soil erosion and tree loss reduced a woodland to a scrub steppe and fed a myth of the Sahara desert relentlessly advancing southward. Over the past two decades this myth has been shattered by the dramatic reforestation of more than 5 million hectares in the Maradi and Zinder Regions of Niger. No single actor, policy, or practice appears behind this successful regreening of the Sahel. Multiple actors, institutions and processes operated at different levels, times, and scales to initiate and sustain this...

Forest transitions (FT) occur when socioeconomic development leads to a shift from net deforestation to reforestation; these dynamics have been observed in multiple countries across the globe, including the island of Puerto Rico in the Caribbean. Starting in the 1950s, Puerto Rico transitioned from an agrarian to a manufacturing and service economy reliant on food imports, leading to extensive reforestation. In recent years, however, net reforestation has leveled off. Here we examine the drivers of forest transition in Puerto Rico from 1977 to 2000 at two subnational, nested spatial scales (municipality and barrio) and over two time periods (1977-1991 and 1991-2000). This study builds on previous work by considering the social and biophysical factors that...

Knowledge of the interplay between ecological and social influences in the context of land-use decision-making is sparse. To help fill this gap, we conducted participatory land-cover mapping in an indigenous territory of eastern Panama to identify factors that influenced household land-use decisions. The map illustrated a mosaic of land cover dominated by pasture. Primary discourse on influences from 35 semistructured interviews with landowners, women, and youth emphasized economic concerns, such as subsistence, and social-cultural factors, such as reticence to abandon traditional agriculture. Multivariate analysis showed that timing of family settlement helped determine proportion of forest cover, and place of origin helped determine proportion of short...

Food-Carbon Trade-offs between Agriculture and Reforestation Land Uses under Alternate Market-based Policies
Provedor de dados: Ecology and Society
Autores: Paterson, Stacey; CSIRO Ecosystem Sciences; University of Adelaide; stacey.paterson@student.adelaide.edu.au; Bryan, Brett Anthony; CSIRO Ecosystem Sciences; brett.bryan@csiro.au.
Understanding the effects of payments on the adoption of reforestation in agricultural areas and the associated food-carbon trade-offs is necessary to inform climate change policy. Economic viability of reforestation under payment per hectare and payment per tonne schemes for carbon sequestration was assessed in a region in southern Australia supporting 6.1 Mha of rain-fed agriculture. The results show that under the median scenario, a carbon price of 27 A$/tCO2-e could make one-third of the study area (nearly 2 Mha) more profitable for reforestation than agriculture, and at 58 A$/tCO2-e all of the study area could become more profitable. The results were sensitive to variation in carbon risk factor, establishment costs, and discount rates. Pareto-optimal...

Autores: Newton, Adrian C; Bournemouth University, Bournemouth, UK; anewton@bournemouth.ac.uk; Premoli, Andrea C; Laboratorio Ecotono, Universidad Nacional del Comahue, Bariloche, Argentina; andrea.premoli@gmail.com.
Forest Landscape Restoration (FLR) involves the ecological restoration of degraded forest landscapes, with the aim of benefiting both biodiversity and human well-being. We first identify four fundamental principles of FLR, based on previous definitions. We then critically evaluate the application of these principles in practice, based on the experience gained during an international, collaborative research project conducted in six dry forest landscapes of Latin America. Research highlighted the potential for FLR; tree species of high socioeconomic value were identified in all study areas, and strong dependence of local communities on forest resources was widely encountered, particularly for fuelwood. We demonstrated that FLR can be achieved through both...

Plants of six species from the Melastomataceae family (Miconia spp. and Bellucia spp.) taken from secondary forest stands of Terra Firme near Manaus, Amazonas, Brazil, were studied with regard to growth form, biometric traits of the plants, morphological and anatomical characteristics of leaves and wood. In addition, plant biomass and the content of mineral nutrients of different parts of the plants were analysed, and xylem flux measurements were carried out to determine the specific water uptake of the plants. The aim of the studies was to detect causal links between the parameters measured and the ecological behaviour of the species as observed in the field, in order to provide an autecological description of the species. The results show that the plant...

Temporary carbon storage and discount rates
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hean,   Robyn L.; Cacho,   Oscar J.; Menz,   Kenneth M.
Several approaches have been proposed for accounting for temporary carbon sequestration in land-use change and forestry projects that are implemented to offset permanent emissions of carbon dioxide from the energy sector. In a previous paper, we evaluated the incentives provided by some of these approaches. In this paper, we investigate further what we call the “ideal” accounting system, where the forest owner would be paid for carbon sequestration as the service is provided and redeem payments when the forest is harvested and carbon is released back into the atmosphere. We demonstrate how discounting affects the net present value of the forest when carbon sequestration is taken into account under this ideal system. Not all carbon is released back into the...

Beginning in the 1970’s the plateaus of Alto Jequitinhonha, northeast of Minas Gerais, until then areas of common use by family farmers, were planted with eucalyptus. This article analyzes the effects of reforestation on land occupation, comparing it with the areas of the family production. It is carried out in the homogenous micro-region of Capelinha, an area with the largest concentration of eucalyptus in the region. Secondary data from the IBGE Census for the years 1970, 1980, 1985 and 1996 were used, and also secondary data from surveys conducted around the region studied, including interviews with management of companies and union leadership. The article concludes that, in thirty years, the reforestation concentrated the land and created reduced...

Autores: Zomer,   Robert J.; Bossio,   Deborah A.; Trabucco,   Antonio; Yuanjie,   Li; Gupta,   Diwan C.; Singh,   Virendra P.
Trees are increasingly grown on-farm to supply wood and biomass needs within developing countries. Over the last several decades, within the irrigated rice-wheat growing lands of northern India, fast-growing poplar trees have been planted on tens of thousands of small farms. Recent debate regarding afforestation has raised the issue that water use is often increased when trees are planted. This ongoing debate focuses primarily on afforestation or reforestation of upland and rain-fed agricultural areas, and off-site impacts such as reduced streamflow. Adoption of poplar agroforestry in northern India, in contrast, is occurring in areas where land and water are already intensively used and managed for agricultural production. This study based on farmer...

Value and Risks of Expiring Carbon Credits from CDM Afforestation and Reforestation
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dutschke,   Michael; Schlamadinger,   Bernhard; Wong,   Jenny L.P.; Rumberg,   Michael.
The Milan conference of the UN Framework Convention on Climate Change has established two types of emission offsets under the Clean Development Mechanism (CDM), valid for afforestation and reforestation activities. In order to account for the non-permanent nature of carbon storage in forests, these credits expire after a predefined periods, after which the buyer needs to replace them. The present article assesses their market value in relation to "permanent" credits, identifies their specific risks and proposes how to mitigate and manage them. It analyzes strengths and weaknesses of expiring credits for sellers and buyers. Taking the example of the EU emissions trading system, the authors discuss how expiring credits could reach fungibility with permanent...

Autores: Saez,   Maria Del Carmen Almansa; Calatrava-Requena,   Javier.
The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other methodological possibilities, whose application to the valuation of this type of project may prove to be of interest. It is the case of the Contingent Valuation Method used for the evaluation of the effects of the Watershead Restoration and Erosion Control Projects of the Aljibe Basin (Almería) Spain, presented here. The results obtained show that, in this case study, application of Contingent Valuation ascribes greater social profitability of the project, with 5.23 % of IRR...

Soil organic matter (SOM) plays an important role in carbon (C) cycle and soil quality. Considering the complexity of factors that control SOM cycling and the long time it usually takes to observe changes in SOM stocks, modeling constitutes a very important tool to understand SOM cycling in forest soils. The following hypotheses were tested: (i) soil organic carbon (SOC) stocks would be higher after several rotations of eucalyptus than in low-productivity pastures; (ii) SOC values simulated by the Century model would describe the data better than the mean of observations. So, the aims of the current study were: (i) to evaluate the SOM dynamics using the Century model to simulate the changes of C stocks for two eucalyptus chronosequences in the Rio Doce...

Autores: Moreira,Milene; Baretta,Dilmar; Tsai,Siu Mui; Cardoso,Elke Jurandy Bran Nogueira.
Araucaria angustifolia (Bert.) O. Ktze., a native forest tree from Brazil, is under extinction risk. This tree depends on arbuscular mycorrhizal fungi for growth and development, especially in tropical low-P soils but, despite being a conifer, Araucaria does not form ectomycorrhiza, but only the arbuscular endomycorrhiza. This study aimed at surveying data on the spore density and root colonization (CR) by arbuscular mycorrhizal fungi (AMF) in Araucaria angustifolia forest ecosystems, in order to discriminate natural, implemented, and anthropic action-impacted ecosystems, by means of Canonical Discriminant Analysis (CDA).

Urban a study was carried out in the Brazilian Amazon (01o 51' S; 60o 04' W). Photosynthetic parameters were measured at increasing [CO2], saturating light intensity (1 mmol (photons) m-2 s-1), and ambient temperature. The rate of electron-transport (J), Apot,and water-use efficiency (WUE) increased consistently at increasing internal CO2 concentration (Ci). Conversely,...

Soils with high acidity and low exchangeable bases may be responsible for low yields of Pinus taeda in a forest plantation at Jaguariaíva, Paraná State, Brazil. The aim of this study was to evaluate the effect of liming and fertilisation, applied over litter, on two selected areas with Pinus taeda plantations. Soil, litter and pine needles were evaluated for K, Ca and Mg concentrations and soil acidity parameters. Seven treatments were applied: (i) complete (N, P, K, Zn, Cu, B, Mo, and lime); (ii) without N, P, and K; (iii) without Zn, Cu, B, and Mo; (iv) without K; (v) without Zn; (vi) without lime; and (vii) control (without nutrients and lime). Soil samples were collected at five soil depths (0-5, 5-10, 10-20, 20-40 and 40-60 cm) simultaneously with...
